Abstract: PURPOSE:To make it possible to exactly control the different sizes of domains of orientation and to make a visual field angle symmetrical and wider by providing the above element with electric field distortion generating sections within pixels in prescribed directions suitable for twisted nematic liquid crystals. CONSTITUTION:An empty cell is assembled by forming pixel electrodes 2 and common electrodes 7 on an upper substrate 20 and applying oriented films 15 consisting of a polyimide A on the respective electrodes. The liquid crystals 14 formed by adding left-hand chiral additives to the nematic liquid crystals and specifying the chiral pitch to 50mum are injected into the empty cell. At this time, the liquid crystal molecules 18 in the central layer of the cell thickness direction are hormzontal to the substrate and are TN oriented. The common electrodes 7 cover the parts exclusive of slits 11. These slits 11 are along the diagonal lines of the pixels by having about inclination 60 deg.. The width thereof is about 6mum and only the parts overlapping on the pixel electrodes are opened. The slits function as the electric field distortion generating sections for distorting the electric fields of the liquid crystal layer in the pixels.

IPC: H04L7/00
Filed: 1988-06-24
Abstract: PURPOSE:To prevent erroneous selection of clock signals by latching two clock signals out of four clock signals, which have 50% duty ratio and have phases successively shifted from one another by 1/4 period, in flip flops(FF) and selecting one pertinent clock signal. CONSTITUTION:Four clock signals CLK1-CLK4 have the same period and have phases successively shifted from one another by 1/4 period and have about 50% duty ratio. FFs 1 and 2 latch clock signals CLK1 and CLK2, which are inputted at the rise point of an input signal DIn at the time of input of the signal DIn, and send latched data 11 and 12 to selectors 3 and 9. An FF 4 latches these data by the rise of a clock signal 13 inputted to a clock terminal C and outputs data 14. Thus, data synchronized with the clock of the receiver side is outputted from the FF in the last stage which phase the input signal is inputted with.

Abstract: PROBLEM TO BE SOLVED: To prevent deviation of bubbles rising from an aerator, to wash the total length of horizontally spread hollow yarn membranes by shearing force of bubbles, and to restrain a rise in differential pressure to prolong continuous operation time. SOLUTION: In a treating tank 10 to which raw water is fed, between two water collecting pipes 12, 13 standing in parallel, a lot of hollow yarn membranes 14 whose end parts each communicate with the inside of the water collecting pipes are installed horizontally and in a vertical multistage manner to form a membrane element 11. A plurality of the membrane elements are installed ranging to constitute a membrane module and also an aerator 15 for generating bubbles is arranged below the membrane module to form an immersion type membrane separator by hollow yarn membrane for gathering permeated water from each membrane element.  In this separator, one 12 of the two water collecting pipes 12, 13 of each membrane element 11 is fixed, and the other water collecting pipe 13 is movably supported in the same horizontal direction as the hollow yarn membranes 14 and also is pulled by a pulling device 20 in the direction in which it is separated from the fixed water collecting pipe 12 to apply tension to the hollow yarn membranes 14. Therefore, since the hollow yarn membranes are linearly strained by this pulling force, the deviation of bubbles from the aerator is eliminated, allowing each one of the hollow yarn membranes to be uniformly washed over the total length thereof.
